42. Cadmium sulfide, Cds, is an insoluble substance with a Ksp of 1.0 X 104º. It dissociates in water according to the following equation: CdS (s) = Cd2+ (ag) + S2- (aq) What is the concentration of the Cd2+ jon in a saturated solution of CdS? A) 1.0 X 10-28 B) 1.0 X 10-21 C) 1.0 X 1014 D) 1.0 X 107 43. BaF2 is very slightly soluble in water with a Ksp = 2.4 X 10$. Which of the following statements is correct? A) BaF2 would be less soluble in 0.10 M NaF than in water. B) BaF2 would have the same solubility in 0.10 M NaF and in water. C) BaF2 would be more soluble in 0.10 M NaF than in water. D) There is no way to compare the solubility of BaF2 in water and in 0.10 M NaF. 44. If the reaction A + B = C has an equilibrium constant greater than 1, which of the following statements is correct concerning the forward reaction? A) The forward reaction is not thermodynamically favored and would be considered non-spontaneous. B) The forward reaction rate is fast. C) The forward reaction is slow. D) The forward reaction is thermodynamically favored and would be considered spontaneous.
